Why's my phone acting like an iFail?

[iviyth0s]

So recently I've lost the ability to multitask, specifically in the way I could jump around from open app to open app and have them still be open as opposed to "restoring" their last state.

It's really annoying and feels alot like an iPhone. If I'm surfing a website or two and go to the text messaging program it's a black screen as if the program had just opened for the first time.
Then if I go back to my browser, all my tabs will "restore" back which is essentially like reloading them all from scratch whereas before I could jump back forth to between the programs and pick right back from where I was without waiting for some "restoring" nonsense.

Does anyone know how to fix this? I've tried different settings in autokiller but that didnt help either

Thanks in advance
